LOG-ROLLING MACHINE.

To all whom it may concern Be it known that 1, PAUL PANGERL, a citizen of the United States, and residing at Rutledge, in the county of Pine and State of Minnesota, have invented certain new and useful Improvements in Log-Rolling Machines, of which the following is a specification.

My invention relates to improvements in log rolling machines or log turners.

An object of the invention is to provide a novel machine for readily rolling or turning a log for the required presentation thereof to the action of the saw, in the sawing operation.

A still further object of the invention is to provide novel means for effecting the movement of the vertically actuated bar, as well as its carrying member or casing, both vertically and in an inclination, to facilitate the turning operation.

The invention consists of certain combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings wherein I have illustrated the preferred embodiment of my invention: Figure 1, is a plan view of a log-rolling machine, constructed in accordance with my invention. Fig. 2, is a sectional elevation taken on the line w-w of Fig. 1, longitudinally of the machine. Fig. 3, is a sectional elevation taken on the line y-y of Fig. 1, and looking toward the left. Fig. 4 is'an enlarged detailed sectional view of the canting or rolling device.

The longitudinal shafts 1 and 2 are arranged in vertical alinement, being suitably journaled in transverse bars of suitable frame work, 3, the latter being arranged be low the floor-line of the structure or building. The shafts 1 and 2, carry friction wheels 1 and 5, at adjacent ends thereof, one secured to each shaft and in alinement with each other, said friction wheels being adapted to be controlled for shifting or moving the same into and out of en agement with friction driving wheels, 6 and F, mountedupon shafts 6 and 7 respectively, by a foot lever 8, and a manually actuated lever, 9, respectively. The manually operated lever 9, encompasses the shaft, 2, and is pivot ed on the frame 3 at 9 to efiect a lateral movement of said shaft with its friction wheel 5, as shown in Figs. 2 and 3, in par- Specification of Letters Patent.

tieular. The foot-levers, 8, have stirrups or bail-llke horizontal upper end portions 10, for the convenient application of the foot thereto, the lower ends of said levers being secured to a collar, adapted to encompass the shaft, 1, as is also disclosed by Figs. 2 and 3, and pivoted to the frame 3 at 10 whereby the lateral movement may be imparted to said shaft and the friction wheel 1, carried thereby. The frame work 3 is slotted to movably receive the shafts 1 and 2, although it is obvious that but very slight movement of the shafts is necessary in order to engage the wheels 4 and 5 with the wheels 6 and 7. V y

The shafts 6 and 7 carrying the friction wheels 6 and 7, are journaled upon a horizontal cross-piece, connecting the upper ends of a pair of legs, 12, and the like connectmg cross-piece of a like pair of legs, 13, spaced therefrom, said shafts carrying the intergeared wheels or pinions, 14, to permit conjoint and simultaneous actuation thereby. Qne of said shafts carries an additional friction wheel, 15, being shown as mounted on the shaft 7 and which is engaged by a belt, 16, designed to receive motion or be driven from a suitable drive mechanism.

The canting device comprises a tubular, tilting casing, 17, initially occupying a vertical position, and pivoted or mounted approximately at its mid-length upon a short shaft, 18, suitably journaled in two transverse members of the frame, 3. The casing, 17, carries a bar, 19, which is provided with upwardly projecting points or teeth, 20, for engaging and aiding the rolling of the log or logs which may be brought into engagement therewith by the log-carriage, as will be readily understood by those skilled in the art. The bar, 19, has a slidable connection with the pivoted or tilting casing, 17, such connection being effected preferably by means of cross-pins 21 and 22, and longitudinal slots, 23 and 2 1. The slot, 23, extends the greater portion of the length of the bar, 19, and the other slot, 24:, extends about two thirds the length of the casing, 17, one cross pin, 22, being fixed to the casing, 17, and received by the slot, 23, and the other crosspin, 21, being carried by said bar, and received by the slot, 24:, each pin being adapted for sliding movement in the respective slots.

The casing, 17, receives its tilting motion through the actuation of shaft, 1, which has a squared portion, -l, to Which is fixed a slotted arm, 26, a link, 27, being pivotally connected at one end to the casing, 17, about centrally of its length below shaft, 18, and at its opposite end to the free end of the arm, 26, within the slot, 28, of the latter.

In order to aid the retention of the tilting casing, 17, in its initial perpendicular position temporarily, a propping bar, 29, is secured to a pin, 29 pivoted at one end to the framework? while its opposite end is adapted to rest against the lower portion of the casing, 17, as seen especially in Fig. 4. The pivotspin 29 projects beyond the'supporting frame, 3, and has a pulley, 29 secured thereto, which is engaged by a belt 29, Which also engages a pulley 29, carried by the shaft, 1, at the'end opposite to the pulley,"4,'for suitably actuating the propping bar 29, in disposing the latter in its effective relation to the casing, 17, as above indicated. The end of the bar, 29, is rounded to properly engage the member, 17, in a cam-like action. The bar 29 swings out ofthe way of casing 17 when the latter is tilted. j

The bar 19, has a rack, 30, extending about tWO-thlI'dS of its length, upon the edge opposite to that having the teeth, 20, with which rack engages a pinion, 31, carried by the shaft '18, said shaft also having a sprocket- Wheel or pulley, 31 fixed thereto and engaged and driven by an endless link-belt, 33, also engaging and driven from a sprocket wheel, 32, carried bythe shaft 2, for transmitting motion to the bar, 19, simultaneously with the tilting or inclining of the casing, 17. The casing, 17, carrying the bar, 19, is arranged to extend above the floor-line to a point about on a level with what may be termed the log deck line, and in the log turning operation, the bar, 19, is run or moved upwardly in an inclination, abovethe log-deck, with its points or teeth presented toward and adapted to engage the required log upon the log-carriage for suitably rollsaw. r

In the use of the shifting lever, 9, the upper friction-pulley, 5, may beadjusted for engagement with either the friction wheel, 6, or the friction wheel, 7, so as to move the bar, 19, outwardly or inwardly with relation to the carrying member or casing, 17, therefor, and by suitably actuating the foot-lever, 8, the friction wheel, l, may be adjusted into engagement with either the friction wheel,

mg or turning the log for the action of the 6, or the pulley, 7, whereby the bar carrying member, 17, may be swung toward or away from the log-deck as may be required in the turning operation.

It will be understood, of course, that, as the several adjustments of the hand and foot levers are effected, the requisite or described movements will be obtained through the belt and gearing operated parts, by means of the shafts l and 2, as disclosed, and their connection with the motor; also, that said levers may be adjusted to neutral position, whereby the operation of the machine may be discontinued temporarily or otherwise.

Having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent, is

l.- A log turner comprising a pivotally mounted frame, a turner bar carried by said frame, means for raising and lowering said turner bar, means for tilting said frame and turner bar, and means operatively connected to said tilting means for locking said frame and turner bar in upright position.

2. A log turner comprising a pivotally mounted frame, a turner bar guided in said frame and having a rack along one edge thereof, a pinion meshing with said rack and mounted upon a shaft, means for reversing the direction of rotation of said shaft, a link connected to said frame, a shaft mounted below said first named shaft and provided with a crank arm pivoted to said link, and means for reversing the direction of rotation of the second named shaft.

3. A log turner comprising a pivota'lly mounted frame, a turner bar carried by said frame, pin and slot guiding means for said turner bar, said turner bar being provided with a rack along one edge thereof, a pinion meshing with said rack and mounted 011 a shaft, means for reversing the direction of rotation of said shaft, a link secured to said frame, a shaft mounted below said first named shaft and provided with a crank arm pivoted to said link, means for reversing the direction of rotation of the second named shaft, and means for locking said frame in upright position.

In testimony whereof I allix my signature in presence of two witnesses.
